Ok, I guess I'll revive this. Describe the chain of infection of Salmonella.

Infectious agent: Salmonella enterica
Reservoir: Food (?)
Portal of exit: Everywhere on the food (?)
Mode of transmission: Food bourne
Portal of entry: Mouth
Susceptible host: animals that eat.

I tried.

A few things wrong
Reservoir and susceptible hosts: Primary hosts are animals such as cattle, swine, and poultry. The final host is humans.
Portal of exit: Skin, respiratory, ailmentary, etc.
Remember, the food is just the vehicle through which the agent gets to the host.


Your turn!

If I remember correctly
Basically an epidemic that occurs within animal population (excluding humans)

Really? They had that on the nats test? Wow.

I'll use some questions I created for a test.

Sum Ting Wong, being the asian he is, goes out for lunch to eat at Hepati- *cough* Genki Sushi. Since he is an extreme asian, he orders 10 orders of rice, which he consumes in less than a minute without a drink. After he finishes, he pays for his meal and goes home, eating nothing except his “meal”. Later that day, Sum Ting Wong experiences vomiting and watery diarrhea. He suspects his meal at Hepati- I mean Genki Sushi had to do with his symptoms.
1. Given this information, what illness does Sum Ting Wong MOST LIKELY have?
2. Given the symptoms, deduce whether the pathogen for this illness is gram-positive or gram-negative (yes, the illness is bacterial)

Question 2 shouldn't be difficult if you can answer Question 1.
For those who don't get my jokes, we had a Hepatitis A outbreak here on Hawaii, that occurred at Genki Sushi, at the time I was making this test.

Answer?
1)Baccilus Cereus commonly can thrive on cooked rice and can cause the symptoms described within the given time frame. He probably has b. cereus poisoning.
2)It is Gram-positive.


I approve of Sum Ting Wong's asian-ness.

Since environmental quality will be the next topic:

At what AQI does the EPA start considereing particulate matter unhealthy for sensitive groups?

Which groups of people are at greater risk from particle pollution(e.g. more likely to manifest health problems)?
